Adopt a polar bear? Have you seen what they do?
How did the polar bear, a vicious killing machine that is thriving, become the poster boy of climate-change alarmism?
Save the whale? That’s so 1970s. Now it’s the mighty polar bear that has become the poster child of the environmental movement. But are polar bears really facing extinction, or are they just a photogenic vehicle for promoting alarm about global warming?
‘Adopt a polar bear’, suggests the green NGO, WWF. WWF will even give you a cuddly toy polar bear for signing up. ‘Many scientists believe polar bears could be gone from most of their current range within 100 years’, says the WWF website, citing climate change as the major threat to the bears. Earlier this month, the US tried – and failed – to persuade the Convention on International Trade in Endangered Species (CITES), to ban cross-border trade in polar bears and their parts. The US lists the polar bear as a ‘threatened’ species, while the International Union for the Conservation of Nature lists it as a ‘vulnerable’ species.
The major claim is that climate change is causing the sea ice in the Arctic to melt earlier and refreeze later. As the press release for a new paper in the Journal of Animal Ecology, released today, suggests, this makes life harder for polar bears. The paper’s researchers tracked female polar bears in the western Hudson Bay area of Canada from 1991 to 1997, and again from 2004 to 2009. According to the lead researcher, Dr Seth Cherry: ‘The data suggest that in recent years, polar bears are arriving on shore earlier in the summer and leaving later in the autumn. These are precisely the kind of changes one would expect to see as a result of a warming climate and may help explain some other studies that are showing declines in body condition and cub production.’
But before we start getting into a lather about the future of nature’s greatest land-based killing machines (sorry, I mean big furry canaries in the climate-change coalmine), it is worth noting that there are more optimistic voices around. Susan Crockford, an adjunct professor at the University of Victoria in Canada, has just produced a short paper for the Global Warming Policy Foundation (GWPF) called Ten Good Reasons Not To Worry About Polar Bears.
Crockford’s first point is that polar bears represent a ‘conservation success story’. The biggest threat to the bears in the past was hunting. Since 1973, when restrictions on hunting were introduced, it is commonly agreed that polar-bear numbers have bounced back from a low of around 10,000 to between 20,000 and 25,000. In addition, four sub-populations of polar bears are currently listed as ‘zero’, says Crockford, because they haven’t been surveyed. Add in those animals, and she argues that the true population figure could easily be between 27,000 and 32,000.
The only population shown to have declined in recent years – a fall in numbers described by Crockford as ‘modest’ – is the one in the western Hudson Bay area. Even here, claims that polar-bear numbers continue to decline are based on data that is ‘unpublished, woefully out of date, or both’, says Crockford. Polar bears have actually shown a remarkable ability to survive and thrive after months without food.
There’s also an assumption that the decline of Arctic ice in recent years must be due to manmade global warming, and that this change in ice conditions must be bad for polar bears. But global temperatures have barely changed since 1997, while the minimum level of Arctic sea ice has halved. That suggests other, more localised factors rather than global warming are responsible. Moreover, as Matt Ridley notes in an introduction to Crockford’s paper, the ‘ideal habit for polar bears is first-year ice that lasts well into the summer, when they feed on fat young seals… The recent trend in most of the Arctic – no change in winter ice extent but a decline in late-summer ice extent – has been towards exactly this ideal combination.’
But striking such an optimistic note does not fit well with the role designated for the polar bear by greens. As BBC wildlife presenter and ‘national treasure’ Sir David Attenborough told the Guardian in 2011: ‘The polar bear is… a very charismatic animal that people can identify with. It’s beautiful, and also savage; it’s got a lot going for it. But it’s only a white grizzly bear, really. All these big issues need a mascot and that’s what the polar bear is.’
By implying that the polar bear is imminently threatened by climate change, and that the polar bear’s fate is a foretaste of our own, green groups have found a creature to embody their crusade to cut greenhouse gas emissions. But polar bears seem anything but in imminent danger. Indeed, WWF argued against any trade ban by CITES as it might weaken the ability to use polar bears as a focus for emissions reductions. ‘We have to focus on what is the major threat and not distract ourselves with a relatively minor one’, WWF’s Colman O’Criodain told BBC News last December.
One of the oddest things about this issue is how polar bears got this cuddly image. A quick look at a polar bear killing and eating a seal should disabuse people of the idea that polar bears are cute. You might as well organise a fundraising campaign to ‘adopt a shark’.
Nonetheless, asking people to ‘adopt a polar bear’ seems to be a great vehicle for fundraising, even though WWF says that the money given will be used for ‘raising awareness of the threats of climate change that we all face’ and ‘will also help fund other essential WWF conservation work around the world’. In other words, those monthly donations may only tangentially benefit polar bears.
The claim that polar bears are under threat is a cynical attempt at emotional blackmail, designed to short-circuit debate about climate change while adding cash to the overflowing coffers of multinational green mega-NGOs. WWF alone reported a worldwide income of over €500million in 2011. Given the apparent health of most polar-bear populations, it’s time the whole fairytale about polar-bear extinction was put on ice.
